ext4: add unmount filesystem message

Browse source 
Now that we have kernel message at mount time, system administrator
could acquire the mount time, device and options easily. But we don't
have corresponding unmounting message at umount time, so we cannot know
if someone umount a filesystem easily. Some of the modern filesystems
(e.g. xfs) have the umounting kernel message, so add one for ext4
filesystem for convenience.

 EXT4-fs (sdb): mounted filesystem with ordered data mode. Quota mode: none.
 EXT4-fs (sdb): unmounting filesystem.
